Possible to still buy 2018 MXdN merch?

They quickly sold out of the couple of styles of event shirts that I liked over the weekend at MXdN, and at $35 a shirt I didn't want to settle for something I wasn't super stoked on, but now I regret not getting one at all (also forgot to buy a nice poster on the way out). Anyone know if they typically still sell MXdN event merch online after the race??
